This would be my suggestion for the complete build, some minor changes from yours.

Took the 500GB drive since it was only $3 more expensive than 250GB.
2133MHz memory isn't really needed but it was the one you picked and it was pretty much the same price as 1600MHz so I left it there.
Better motherboard which is also cheaper.
Slightly better PSU, 520W is plenty for a single GPU build.

Would that motherboard let the ram run full speed? I'm reading in the reviews some motherboards limit ram speed.

Keep in mind, usually increasing the RAM above 1600 really won't give much benefit. I guess there's not a downside to it, per se. However it's not something to really 'worry' about. Again, ram is so cheap, that getting normal 1600 ram would only save you about $8.
